The refraction of light by the cornea and lens of the eye makes it possible for an image to form on the retina. Without the formation of an image, it would be possible for the retina to detect the presence or absence of light, but not shapes or objects.

Does refraction take place in opaque objects?

Refraction is the phenomenon which allows light to pass from one medium into the other. But opaque object will not allow light to pass through. So refraction becomes impossible in case of opaque objects.


How does refraction affect the appearance of the sky?

The sky is blue because of refraction. Sunsets and sunrise are so beautiful because of refraction. If there was no refraction, we would see the sky as a black expanse.


What is a good link to see pictures of light refraction?

A good place to see pictures of light refraction is on Google Images or science websites such as National Geographic or ScienceDaily. You can search for "light refraction" or "photos of light refraction" to find a variety of images showcasing this phenomenon.

What has to be different to allow refraction to occur?

Refraction occurs when light passes between materials of different optical densities, causing a change in its speed and direction. The change in speed must be coupled with a change in direction to enable refraction to occur.


Does a periscope use an refraction?

Yes, a periscope uses reflection, not refraction, of light to allow an observer to see objects that are not in their direct line of sight. Light enters through one end of the periscope, reflects off a series of mirrors or prisms, and exits through the other end to provide an observation at a higher or lower vantage point.

Imagine that you are a fish underwater When you look up to the surface to the water you can see the sky and also the bottom of the pool How do you explain this unusual view?

Reflection and refraction. You see the reflection on the bottom of the surface of the pool. You see the refraction of light through the surface of the pool. This is the super short answer...someone else might provide more information but the reader can "google" reflection and refraction to find out more.
